Bean Beetles (callosobruchus maculatus 32oz)
If you’ve ever dealt with fruit flies getting loose in your house, this is your upgrade.
These are flightless bean beetles (Callosobruchus maculatus)—a clean, contained feeder that stays exactly where you put it. No buzzing around. No chasing flies. Just a steady supply of small, active prey your animals will actually hunt.
Each 32 oz culture comes alive and ready to work:
- Flightless adult beetles (~3 mm / 1/8 inch)
- Established starter colony
- ~50 mL of black-eyed peas/pinto bean mix as the breeding base
They’re about the size of fruit flies, but without the chaos.
Why They Work
We don’t use a single bean—and that’s intentional.
Our cultures are raised on a blend of pinto beans and black-eyed peas, which:
- Supports more consistent production
- Provides a broader nutrient base
- Helps maintain culture stability over time
You get a more reliable feeder, not just a container of bugs.
Production:
At proper temps (75–85°F), this culture turns into a machine:
- Adults lay eggs directly on the beans
- Larvae develop inside (no smell, no maintenance)
- New beetles emerge continuously
You’re not buying 50 bugs.
You’re buying hundreds over the next few weeks.
Feeding
Tap them out and go:
- Use a feeding cup
- Dust with calcium if needed
- Feed immediately
They move enough to trigger feeding without overwhelming smaller animals.
Disposal (Do This Right)
These are agricultural pests.
When finished:
- Freeze for at least 72 hours
- Then dispose
Best For
- Dart frogs
- Small geckos
- Baby chameleons
- Other micro-predators
Bottom Line
If fruit flies are a headache, this is the fix.
Controlled. Productive. Low maintenance.
Built to work—not to escape.
